What should come in place of the question mark (?) in the given series?
4,9,24,69,204,?

Information Given:
Series: 4, 9, 24, 69, 204, ?

Logic: Pattern: (Previous × 3) − 3

Explanation:
9 = 4×3 − 3
= 12 − 3 = 9

24 = 9×3 − 3
= 27 − 3 = 24

69 = 24×3 − 3
= 72 − 3 = 69

204 = 69×3 − 3
= 207 − 3 = 204

Next = 204×3 − 3
= 612 − 3
= 609

Final Answer:
609

Final Correct Option:
(a)
